SPRING-BED-BOTTOM STRUCTURE.

Specification of Letters Patent.

Patented July 12, 1921.

Application filed. Eeptember 22, 1920. Serial No. 411,891.

To all whom it may concern:

Be it known that 1, lViLLIAM l3. ANDER- soN, a citizen of the'United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Spring-Bed-Bottom Structures, of which the following is a specification.

The invention relates to improvements in spring bed bottom structures.

It has especial reference to corner brackets used to connect the side and end rails of the surrounding frame.

One of the objects of the invention is to reduce the cost of construction.

Another object is to strengthen the joint between the end and side rails by use of a bracket that requires only a single rivet to connect the members together.

Another object is to provide a bracket which cover the salient, sharp edges of the end rails thereby contributing to the orna mental appearance of the bed frame and providing additional holding means that strengthens the structure and prevents warping and distortion of the frame.

Other, further and more particular objects of the invent-ion will become readily apparent, to person skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein Figure 1 is a fragmentary view of one end of the spring bed bottom showing parts broken away and other parts in section.

Fig. 2 is a section taken on line 22 of Fig. 1 through one of the end rails showing a side view of the brackets.

Fig. 3 is a section taken on line of Fig. 2.

Fig. 4: is a plan view of part of one bracket with parts broken away.

Fig. 5 is a plan view of one end of an end rail.

1n all the views the same reference characters are employed to indicate similar parts.

10 represents a plan view of a portion of the bed springs with the end rail 11 connected to the side rail 12 by means of the intermediate bracket 18. The end of the side rail extends into the socket 14 of the bracket. The side rails are preferably oval in form so that the brackets will not shift circumferentially around the axis of the side rail. A bracket member 15 rises obliquely from the socket member 1a and is provided with an angular terminal end 16 having a vertical -7 r wr w .leg 1! and a hoiinontal leg 18. This portion 18, of the structure, is angular in plan, shown at 19 in Fig. .1:. The lower end of leg 17 is connected to the rib 20 of the ver tical member 15 while the rib 21 is connected to the extreme end of the horizontal member 18. This form of construction provides greater strength with minimum quantity of metal. Under the leg 18 there is a laterally extending flange 22, which constitutes part of the vertical leg 17, and by which the bracket is connected to side rail 11 by means of a single rivet 23.

The web 17 of the structure is continued on the opposite side of the rib 21, on the upstanding member 15, and. is rounded and thickened, as at 24, in Fig. 4, to provide a shoulder 25. Overlying the curved part of the web 17 is a ledge 26 terminating at the end of the curve, as at 28, in an overhanging point 29. The end rail 11 is provided with a shoulder 30. The vertical leg 31 of the end rail 11, lies against the flat outer surface of the web 17 and abuts against the shoulder 25. The curved part 82 extends under the ledge 26. The parts 33 and 2341 contact the curved portion of the web 17.

The cut-away portion leaves the part 35 inwardly removed from the surfaces of the salient edges 38 and 3 1 so if any unevenness should extend between the location. of parts 33 and 31- under the ledge 26 or on the web 17, it will not be necessary to clear it away before the bracket is secured to the end rail, thereby saving time and labor in assembling the different parts. After the end, of the end rail 11, is placed under the ledge 26 with its vertical leg in contact with the web 17, and its end abutting shoulder 25, then the rivet 23 is inserted in the perforation in the laterally extending web 22, a continuation of 17, and through the vertical leg 31 of the end rail, and after the parts have been so secured together, the terminal point 29 is bent down over the front edge 36 of the end rail, as shown in Figs. 2 and 3.

The lower portion of the extending curved part 17. of the bracket, is connected by an upstanding member 37 and a cross member. 38 to the socket 141.

The ledge 26 overlying the web 17 completely covers the salient curved edge of the end rail, contributes to the ornamental appearance of the structure and to the means for attaching it tothe end'rail by supple menting the eflfect of the single rivet 23 in holding the parts together.

Having described my invention what I claim as new and desire to secure by Letters Patent is l. A bed bottom cornebracket comprising: an arm having a socket at one end for holding a side rail, an outwardly curved vertical web at the upper end of the arm andv against which the curved end of an end rail may abut, 'and a ledge extending inwardly from the upper curved edge of the web for overlying and covering the joint with the end rail and strengthening the same.

2. A. corner bracket having a socket to end rail is to abut and a ledge 26, overlying the circular part of the vertical leg to cover the rounded end of the horizontal leg of the end rail and extending therebeyond, the ex-' tended end to be subsequently bent over the inner horizontal portion of the end rail, whenthe latter is attached to the bracket.

In testimony whereof I hereunto subscribe my name.

WILLIAM B. ANDERSON.
